摘　　要：针对半潜式钻井平台的主尺度优化问题,提出一种改进后的Analytic Hierarchy Process-Criteria Importance Though Intercriteria Correlation(AHP-CRITIC)主客观赋权法。基于响应面优化法得到设计变量与目标函数之间的函数关系,采用多目标遗传算法(Multi-Objective Genetic Algorithm,MOGA)对第七代半潜式平台主要构件尺度进行优化,得到Pareto前沿和3组最优解集,与原始方案比较发现各项水动力性能均有明显改善,且整体用钢量显著降低。对原有的单一主观或单一客观的评价决策方法进行改进,将二者结合,采用AHP与CRITIC赋权法结合的方法对最优解集的不同方案进行评估,得到一个既满足决策者的主观期望,又符合各指标之间相关关系规律的最优主尺度方案。该种基于综合性能的自动寻优决策方法高效合理,与单一评价方法相比更加全面,可应用于实际工程初步设计主尺度确定。An improved Analytic Hierarchy Process-Criteria Importance Though Intercriteria Correlation(AHP-CRITIC)subjective and objective weighting method is proposed for the optimization of the main dimensions of semi-submersible platform.Based on the response surface optimization method,the functional relationship between design variables and objective function is obtained.The Multi-Objective Genetic Algorithm(MOGA)is used to optimize the dimensions of the main components of the 7th generation semi-submersible platform.The Pareto front and three sets of optimal solutions are obtained.Compared with the original scheme,the hydrodynamic performance is significantly improved and the overall steel weight is significantly reduced.The original single subjective and single objective decision-making methods are combined and improved by AHP-CRITIC combined method to evaluate three different sets of the optimal solutions,which can satisfy both the subjective expectation of decision maker and the laws of correlation among the indexes.Compared with the single decision-making method,the combined method is more comprehensive and reasonable,and can be applied to determine the main dimensions of the preliminary design of practical projects.
